CONNECTING THE LOADS
Applying The Load
Allow the engine to warm up for two or three minutes before
applying any load. This will allow the engine to reach
normal operating temperature and oil to circulate
throughout the engine. A short warm-up time will permit
the engine to work more efficiently when the load is applied
and will reduce the wear in the engine, extending its life.
Receptacles have been provided to allow loads to be
connected to the generator. The loads should be added
one at a time. If a large motor is being started or multiple
motors are being started, they should be started
individually and the largest should be started first.
CAUTION: EQUIPMENT OVERLOAD
Keep the generator load within the generator and
receptacle nameplate rating. Overloading may cause
damage to the generator and/or the loads .
Most electric tools and appliances will have the voltage and
amperage requirements on their individual nameplates.
When in doubt consult the manufacturer or a local
electrician. The nameplate amperage rating for electric
motors can be misleading. See “Starting Electric Motors” in
Unit Capabilities (page 3).
These engine generator sets are inherently self regulating
based on engine speed. The engine governor will
automatically adjust itself to the load. No harm to the
generator will result if it is operated with no load connected.
Proper utilization of the receptacles located on the control
panel is necessary to prevent damage to either the
receptacles or the generator. The generator is a limited
source of electrical power, therefore pay special attention to
the receptacle and generator ratings. The nameplate rating
can be obtained through a single receptacle as long as the
receptacle amperage rating is not exceeded.
Grounding
All units must be grounded. Drive a 3/4 or 1" copper pipe
or rod into the ground close to the engine-generator set.
The pipe must penetrate moist earth. Connect an
approved ground clamp, to the pipe. Run a no. 10 Awg wire
from clamp to the generator ground lug on the “receptacle
panel”. Do not connect to a water pipe or to a ground used
by a radio system.
The engine-generators covered in this manual were
designed for portable use. DO NOT OPERATE INDOORS.
The unit should be stored in a warm dry location. Move the
unit outdoors to a flat dry location for use.
WIRING
Plug your tools such as drills, saws, blowers, sump pump
and other items to be powered directly into the generator
receptacles. Before plugging in all the tools and cord sets,
recheck the rating of the generator set. Be sure it can
handle the intended load and is compatible with the
voltage, phase, and current ratings.
screen and muffler areas.

Store in a clean and dry area.
Note: The use of a fuel additive, such as STA-BIL, or an
equivalent, will minimize the formation
of gum deposits
during storage. Such an additive may be added to gasoline
in the
engine’s fuel tank or to gasoline in a storage
container.
OPERATING SPEED
The engine-generator must be run at the correct speed in
order to produce the proper electrical voltage and frequency.
CAUTION: EQUIPMENT DAMAGE
The output voltage should be checked to insure the generator
is working properly prior to connecting a load to the generator.
Failure to do so could result in damage to equipment plugged
into the unit and possible injury to the individual.
All engines have a tendency to slow down when a load is
applied. When the electrical load is connected to the
generator,the engine is more heavily loaded, and as a result
the speed drops slightly. This slight decrease in speed,
together with the voltage drop within the generator itself,
results in a slightly lower voltage when the generator is
loaded to its full capacity than when running no load. The
slight variation in speed also affects the frequency of the
output current. This frequency variation has no appreciable
effect in the operation of motors, lights and most appliances.
However, electronic equipment and clocks will be affected if
correct RPM is not maintained. See Load vs. Output chart.
Although individual units and models may vary slightly, the
normal voltage and frequency of the engine-generators
described in this book are approximately as follows, under
varying loads:

*Portion of plant’s rated output current.
The speed of the engine was carefully adjusted at the factory
so that the generator produces the proper voltage and
frequency. For normal usage, the speed setting should not
be changed. If the generator is being run continuously on a
very light load, it is often advisable to lower the operating
speed slightly. Whenever making any speed adjustments
check the unit with a voltmeter or tachometer and be sure the
speed is correct.
Lower voltage may damage both the generator and any load
connected to it. Running the engine at excessively high
speeds results in high voltage, which may significantly
shorten the life of appliances being used.
Output voltage should be checked periodically to ensure
continued proper operation of the generating plant and
appliances. If the generator is not equipped with a voltmeter,
it can be checked with a portable meter. Frequency can be
checked by using an electric clock with a sweep second
hand. Timed against a wrist watch or a stop watch the clock
